+1000HP N54s are coming sooner than later. Someone is going to need to provide a standalone EMS very soon. Has anyone contacted AEM or Haltech to see if they're working on one? @undercover how is the ProEFI coming along?

Don't be a hater. Everyone knows you're an "M" nutswinger. If it's not an Sxx motor it's a POS. You have the only S65 in the 700HP realm. You can't honestly say that there won't be many more N54s closer to 1000HP than S65s. You're such a fanboy. We still love you though haha.

No I'm a realist. Fueling issues aren't even solved and people are making 1000 hp claims on paper. Come on now.

And no, I don't have the only one in the 700 hp realm or wheel hp realm and things are about to get far more interesting.

I can honestly say there will be more 1000 hp S65's because that's the truth. One step at a time.

Others have shown SOME are cast yes. Rumor was that eariler ones were forged. I thought I remembered pictures of forged pistons coming out of an N54 but I can't confirm that. My memory is fading is I grow older LOL.

I had a engine that skipped timing/broken chain and the cylinder head is useless it seems. Are you able to fix these issues with your rebuild solution? Also would the block have sustained any damaged as a result?
Thanks!

we're all still hoping the proEFI really pulls through, as it also will let you keep the factory ECU for comfort stuff.

@Flinchy that was an awesome link you posted with the Motec N55!!!! Im not sure if im believing my eyes....it has a turbo upgrade for sure and running on a Motec standalone successfully..

They even mention in the posts and comments that the guy who built it has also ran a Motec standalone on a N54 before too??? Someone needs to get in contact with this guy for more info...Wonder if he had an upgraded turbo on the N54 as well

yeah i was just as surprised as you haha

it's a wonder how it was done and literally has all of a single post on the whole internet!

I was able to remove this cassette within 10 minutes of working on it.

One of the cam bearing ledges is bad. Can you see which one? This bums me out, because they are REALLY expensive to replace.... and they WILL be replaced, because the new owner I'm sure doesn't want to mess with vanos faults

The head is a little gooey, but not super bad.

Uh oh. Do you see what I see? Bad news

Got the engine tore down. The pistons on this one show 24/06 (IIRC).... so I'm *assuming* this engine is an ultra early 2007 car..... like first engines out there.......

Eww bummer. spun rod.

Another picture. The bearing is "melded" to the rod. (my word for welded/melted)

So in any case, the story with this engine was, the turbos blew a seal (go figure! lol), The customer did not care/pay attention to the oil level condition or warnings, and it starved of oil.

It just spun the bearing a little bit. The crank can be saved very easily. I dont know if it will even need .010 to clean up.

So, another one tore down to compare stuff. Guess Ill have to dig out the other ones I have/know where they are, and see whats up with those
